Summary A lifeguard who drowns? In the case of Daniel Seeger, the head of the local DLRG station had to be incapacitated with knockout drops. Nele and Paul investigate the dead man's professional environment and come across his assistant Leon Berg. The quiet drone expert and motorcycle freak is obviously playing a double game. Then there is the argumentative environmentalist Carl Weyrich, who felt disturbed by the bathers and provoked by Daniel. Is that a motive for murder? The WaPo team realizes that they have to operate in a completely different way. Because little by little, more and more victims of knockout drops are found who almost drowned. For Nele, the case thus takes on a personal dimension. Her son Niklas, who is skipping school and wants to move out, is in mortal danger. And Anna, who knows Noah from school, is also part of the DLRG team. She is happy with her colleague Yannik. Meanwhile, Nele's mother Mechthild is working on a plan to keep the family together.
